To add to what InaneCathode said it might be a good ides to put as much oil in each cylinder as you can. Then take a blower nozzle that will fit inside the spark plug opening and squirt some air in there so the oil can get to the top of the cylinder bore. This will be messy. Vinegar is also a great thing to use instead of oil but after it frees up you need to use oil.
Hot, humid air is less dense than cooler, drier air. This can allow a golf ball to fly through the air with greater ease, as there won't be as much resistance on the ball.
Ok been a while since august but only just had time to get this done. loaded up with oil on friday and left it to soak for a bit. Been trying to get it to turn by hand on and off all over the weekend but no luck!! Not gonna be able to do much till thursday now so maybe it'll soak in and be OK, if not.....any more ideas? Not keen on a rebuild as at this stage its only to move it about while I repair the body....
I had a car which ran great, washed it off ,and engine, before going into storage.DUMB!
two years later, engine is seized... rust on plugs 3 and 4...
Sooooo,i did the old "cola in the cylinders".. yup, coke works best, has something called orthophosphoric acid in it, I think... 48 hrs later, with a bit of massaging of the flywheel with a crowbar,to get it to turn, and presto!!! now turns over by hand, some oil in cylinders, drain sump and voilà.
Probably not the healthies engine I've got, but in a pinch...
just make sure you run it a bit to get that cola 100% gone and covered in oil
a dash of mystery or something down the intake to hit the valves would be nice too
give a man a watch and he'll allways know what time it is. give him two and he can never be sure again.
Things are rarely just crazy enough to work, but they're frequently just crazy enough to fail hilariously.
Well, ill be........ not tried it on the engine in question but suggested it to a mate with the same problem. tipped it in on thursday turning easy by the weekend. bit worried about getting it all out though.
My engine thats siezed had new barrels and pistons in just before i let it stand. Would you still think this is the way to go.
Great! I'm so happy one of my crazy tips was able to help someone out....
The thing about cola is it attacks rust and carbon, but isn't too agressive on solid metals, in the short term. Having said that, if it were my engine, (remember, I said last resort, and I only do this with engines which are not otherwise worth fixing before a complete tear-down), and had new P/C, I would take the time to dissassemble, and gently remove pistons with a puller and a block of wood, and plenty of WD-40, to inspect, and eventually re-hone.
special P/C kit (more expensive than stock)?
It really depends on how much you earn per hour, and how expensive the P/C set was, vs. how much time it would take you to do it right divided by the time you would save with the cola trick.
But it sure is fun when it works right, for so little effort.....
